2007. A. Check out eddy current separation on the web; this equals a gold magnet! Non-magnetic conductors e.g. gold, silver, copper, etc. can have electric fields inducted into them. These electric fields attract and repel just as do magnetic fields.
Metal detectors are able to find non-magnetic metals, like gold or silver, using a principle called the Lenz effect. Moving the metal detector over a gold coin will set up a slight electric field in the coin. The metal detector can sense this field and alert you to the coin. This also works with aluminum and copper.
Like pure gold, fine .999 silver is not magnetic and in fact, should slightly repeal from a strong magnet. Below we will break down scientifically why this is so. In elements we come across in our daily lives only iron, nickel, cobalt, gadolinium, neodymium, and samarium are highly attracted to magnetics.
Most gold used in jewelry is actually a mix of silver and gold. Like gold, silver isn't attracted to a magnet. There may even be other metals like copper, platinum, or nickel mixed with the gold to give it different colors. They also make it harder so it doesn't bend or scratch. So even if you gold isn t magnetic that doesn t mean it s pure.
Apr 08, 2019· Sample 251179 graded 1.11% copper (0.04 soluble copper) and 33.70% iron. Both had measureable amounts of gold, silver, vanadium and cobalt. The samples were crushed and milled, then passed through magnetic drums to separate magnetic iron. Sample 251178 then assayed 0.61% copper and 69.32% total iron. Sample 251179 tested 1.19% copper
